                       TITLE 26--INTERNAL REVENUE
 
    CHAPTER I--INTERNAL REVENUE SERVICE, DEPARTMENT OF THE TREASURY 
                               (CONTINUED)
 
PART 1_INCOME TAXES--Table of Contents
 
Sec. 1.166-8  Losses of guarantors, endorsers, and indemnitors incurred 
on agreements made before January 1, 1976.

    (a) Noncorporate obligations--(1) Deductible as bad debt. A payment 
during the taxable year by a taxpayer other than a corporation in 
discharge of part or all of his obligation as a guarantor, endorser, or 
indemnitor of an obligation issued by a person other than a corporation 
shall, for purposes of section 166 and the regulations thereunder, be 
treated as a debt's becoming worthless within the taxable year, if--
    (i) The proceeds of the obligation so issued have been used in the 
trade or business of the borrower, and
    (ii) The borrower's obligation to the person to whom the taxpayer's 
payment is made is worthless at the time of payment except for the 
existence of the guaranty, endorsement, or indemnity, whether or not 
such obligation has in fact become worthless within the taxable year in 
which payment is made.
    (2) Nonbusiness debt rule not applicable. If a payment is treated as 
a loss in accordance with the provisions of subparagraph (1) of this 
paragraph, section 166(d), relating to the special rule for losses 
sustained on the worthlessness of a nonbusiness debt, shall not apply.

[[Page 921]]

Accordingly, in each instance the loss shall be deducted under section 
166(a)(1) as a wholly worthless debt even though there has been a 
discharge of only a part of the taxpayer's obligation. Thus, if the 
taxpayer makes a payment during the taxable year in discharge of only 
part of his obligation as a guarantor, endorser, or indemnitor, he may 
treat such payment under section 166(a)(1) as a debt's becoming wholly 
worthless within the taxable year, provided that he can establish that 
such part of the borrower's obligation to the person to whom the 
taxpayer's payment is made is worthless at the time of payment and the 
conditions of subparagraph (1) of this paragraph have otherwise been 
satisfied.
    (3) Other applicable provisions. Other provisions of the internal 
revenue laws relating to bad debts, such as section 111, relating to the 
recovery of bad debts, shall be deemed to apply to any payment which, 
under the provisions of this paragraph, is treated as a bad debt. If the 
requirements of section 166(f) are not met, any loss sustained by a 
guarantor, endorser, or indemnitor upon the worthlessness of the 
debtor's obligation shall be treated under the provisions of law 
applicable thereto. See, for example, paragraph (b) of this section.
    (b) Corporate obligations. The loss sustained during the taxable 
year by a taxpayer other than a corporation in discharge of all of his 
obligation as a guarantor of an obligation issued by a corporation shall 
be treated, in accordance with section 166(d) and the regulations 
thereunder, as a loss sustained on the worthlessness of a nonbusiness 
debt if the debt created in the guarantor's favor as a result of the 
payment does not come within the exceptions prescribed by section 
166(d)(2) (A) or (B). See paragraph (a)(2) of Sec. 1.166-5.
    (c) Examples. The application of this section may be illustrated by 
the following examples:

    Example (1). During 1955, A, an individual who makes his return on 
the basis of the calendar year, guarantees payment of an obligation of 
B, an individual, to the X Bank, the proceeds of the obligation being 
used in B's business. B defaults on his obligation in 1956. A makes 
payment to the X Bank during 1957 in discharge of his entire obligation 
as a guarantor, the obligation of B to the X Bank being wholly 
worthless. For his taxable year 1957, A is entitled to a deduction under 
section 166(a)(1) as a result of his payment during that year.
    Example (2). During 1955, A, an individual who makes his return on 
the basis of the calendar year, guarantees payment of an obligation of 
B, an individual, to the X Bank, the proceeds of the obligation being 
used in B's business. In 1956, B pays a part of his obligation to the X 
Bank but defaults on the remaining part. In 1957, A makes payment to the 
X Bank, in discharge of part of his obligation as a guarantor, of the 
remaining unpaid part of B's obligation to the bank, such part of B's 
obligation then being worthless. For his taxable year 1957, A is 
entitled to a deduction under section 166(a) (1) as a result of his 
payment of the remaining unpaid part of B's obligation.
    Example (3). During 1955, A, an individual who makes his return on 
the basis of the calendar year, guarantees payment of an obligation of 
B, an individual, to the X Bank, the proceeds of the obligation being 
used for B's personal use. B defaults on his obligation in 1956. A makes 
payment to the X Bank during 1957 in discharge of his entire obligation 
as a guarantor, the obligation of B to X Bank being wholly worthless. A 
may not apply the benefit of section 166(f) to his loss, since the 
proceeds of B's obligation have not been used in B's trade or business.
    Example (4). During 1955, A, an individual who makes his return on 
the basis of the calendar year, guarantees payment of an obligation of Y 
Corporation to the X Bank, the proceeds of the obligation being used in 
Y Corporation's business. Y Corporation defaults on its obligation in 
1956. A makes payment to the X Bank during 1957 in discharge of his 
entire obligation as a guarantor, the obligation of Y Corporation to the 
X Bank being wholly worthless. At no time during 1955 or 1957 is A 
engaged in a trade or business. For his taxable year 1957, A is entitled 
to deduct a capital loss in accordance with the provisions of section 
166(d) and paragraph (a) (2) of Sec. 1.166-5. He may not apply the 
benefit of section 166(f) to his loss, since his payment is in discharge 
of an obligation issued by a corporation.

    (d) Effective date. This section applies only to losses, regardless 
of the taxable year in which incurred, on agreements made before January 
1, 1976.
